Songraphic Assessment of Lower Extremity Arterial Grafts

Abstract

Arterial bypass grafts are used to improve blood flow in the lower extremities, and ultrasound is often used to monitor these grafts after place ment. The types of grafts used in the lower extremities are reviewed, and the use of sonog raphy to evaluate these grafts is illustrated.
